I've got one of those big pots for tube work at home. t isn't practicla on a ride, too big. When the same discussion appeared in r.b.t a few years ago, I decided that quantity might be a suitable substitute for quality. I bought 30x tubes of cheap Chinese glue at a cost of about $0.50 per tube. https://www.ebay.com/itm/153039763013 That's the stuff used in bike shops and I've never seen them drying up either. I suspect that the contents are different. They certainly do dry up eventually. I leave a few tubes in my car in the automobile tire patch and plug kit. The tubes are larger, but the contents seems like the same glue and solvent. The tubes dry out after about a year in hot car. I suspect that the Rema "cold vulcanizing fluid" type adds some kind of vulcanizing accelerator to deal with the unvulcanized rubber patch. One thing I haven't tried is marking the tubes with their measured weight, to see if I can at least identify which tubes are lacking contents. Also, I've never seen a dry tube that still has some residual liquid rubber cement left. It's always good as new, or containing a small amount of some kind of white powder, and nothing else. Weird. I have seen plenty where there was still "liquid" in it but most of it had become gooey and clumped up on when squeezed out onto the tube surface.

I've found the Rema Tip-Top patches with their tubes of cold vulcanizing fluid to work extremely well. After recommendations in this NG I bought a larger pot with tube cement and with a dabbing tool mounted inside the lid. I have used that on various patches and it worked well. It's just way to large to carry along in a pannier. Be scrupulous about sealing. The 8oz cans with a brush are a great value, but they dry out pretty quickly and inevitably before a home mechanic can use them up. Nonetheless, considering the price difference between the tubes and cans, you still come out ahead even with wastage. It's like buying the big bottle of hydraulic oil -- for twice the price, you get ten times more.. You can spill half of it on the floor and still come out way ahead. -- Jay Beattie. |

That might be. You live near the coast where it rarely goes above 80F. Here we have weeks in a row where it's above 100F during the day and I ride in almost any weather. Even at 105F in the glistening sun when the bike paths are almost empty. When I grab another bottle of water out of the left pannier after a few hours it's really hot. Everything bakes. -- Regards, Joerg http://www.analogconsultants.com/ |
